环氧丙烷储罐泡沫灭火系统设计
|
摘要
沸点低于45℃的环氧丙烷易燃液体灭火采用七氟丙烷气体泡沫灭火系统,其利用空气泡沫对环氧丙烷等低沸点可燃液体进行的灭火,普通空气泡沫难以彻底扑灭该类液体火灾,对环氧丙烷等液体甚至无法控火。用七氟丙烷灭火剂替代空气发泡的七氟丙烷气体泡沫灭火技术,对于沸点低于45℃的环氧丙烷易燃液体灭火性能良好。七氟丙烷气体泡沫灭火系统容易实现工程应用,在普通泡沫灭火系统的基础上,增加七氟丙烷供给系统即可实现七氟丙烷气体泡沫灭火。
The heptafluoropropane air foam fire extinguish system is adopted to extinguish the fire caused by flammable liquid with boiling point below 45 degrees such as propylene oxide. Based on the fire extinguishing test on propylene oxide, ordinary air foam cannot completely extinguish such fire or even cannot control the fire caused by propylene oxide. The use of heptafluoropropane fire extinguishing agent instead of heptafluoropropane air foam fire extinguishing technology has good fire extinguishing performance for fire caused by flammable liquid propylene oxide with boiling point below 45 °C. The heptafluoropropane air foam fire extinguishing system can be easily applied in engineering. The heptafluoropropane air foam extinguishing system can be realized by adding the heptafluoropropane supply system on the basis of the ordinary foam fire extinguishing system.
